Hey, I'm Dimitris from Greece, and let me first say that the app is awesome and it's the one I ended up with while trying and searching many..many.. MANY apps.
I do have a few questions for anyone that can help me out.
1) Is there a dark mode on Mac OS? I didn't find anything in the settings, and if not is it coming?
2) As I understand the Reading Lists are just lists that we create with drag-n-drop, like making events or character reading orders etc., but, what are the tags for? Since I can edit a comic and add on "genres" any tags I want that are searchable, what do I need the tags(labels) for? Since I can name any reading list whatever I want, which is the same as a label. Sorry, just trying to understand.
3) When you right click on a comic, what is the "# Assign current order to comics"?
4) Can I somehow set a custom folder icon that I've made in photoshop for example for my folder on Finder, but have it also as a cover on my subfolder on YACReaderLibrary instead of having the first comic cover showing that's inside? To have different series/volumes that way.
5) Again, Can I change the folder icons on the sidebar on YACReaderLibrary to logos instead of a publisher/character/whatever I want?
6) If I transfer my Library to an External HD (which is where I want to have it and continue when the hd arrives) how do I go about it to have YACReaderLibrary read it every time I connect it to my mac? If the external hd is connected will the app read the library? Will I have to create a new library every time I connect the external hd?
7) What is the "Close to Tray" on settings?

What does the pack/unpack covers do?
9) Can we have more info added that we can add manually? Like Variant Covers, Country, Language (comics in different language), info about characters, price etc.?
Thanks a lot and sorry for the many questions!
